JOHN A. BOIVLER, OF NEWV YORK, N. Y.

TWISTED M ETALLIC BAND.

SPECIFICATION forming part of Letters Patent No. 494,975, dated April 4,1893.

Application file'd April 29, 1892. Serial No. 431,213- (No model.)

To all whom it may concern:

Be it known that I, J OHN A. BOWLER, a citizen of the United States, anda resident of New York, county and State of New York, have invented anew and useful Improvement in Twisted Metallic Bands, of which thefollowing is a specification.

This invention has for its object to produce a twisted metallic bandhaving the general appearance of two wires twisted together and adaptedto be used for all purposes that twisted wires are, or can be, appliedto.

It consists of a strip of metal made, by means of suitably formedrollers, or otherwise, with a thin central longitudinal web and beadedor thickened edges twisted in such a manner that the two beaded orthickened edges will appear as two pieces of wire twisted togethercombined and connected together by a thin central web integraltherewith.

For industrial purposes my improved twisted band has many advantagesover twisted wires of equal weight per given length, in that it is morerigid, has greater tensile strength, will not stretch so readily and isless expensive to manufacture. As abox strap, one of the principal usesfor which it is well adapted, the central web will be made sufficientlythin to admit of nails being driven through it without punching orpreviously forming the nail holes, so that the nails may be driventhrough the web between the thickened edges anywhere throughout itslength and also close to' its ends, thereby forcing and holding theextreme ends of the band in close contact with the box or other articleto which it is applied.

In the accompanying drawings, to which I will now refer, Figure 1represents a piece of twisted metal band made according to my invention.Fig. 2 is a transverse section of the strip of metal from which it isformed. Figs. 3, a, 5 and 6 represent a few modifications, by transversesectional views, in the shape of strips of metal adapted to be used inmaking my twisted band, and Fig. 7 represents part of a case or box towhich is applied the twisted band as a box strap.

In the manufacture of this article, the metal is formed into long stripsor ribbons having the characteristic form shown in Fig. 2, that is, athin central web Z) and two thickened or beaded edges a, a integraltherewith, the crosssection of said edges being circular as shown, sothat when said strip or ribbon is twisted as shown in Fig. 1, it is, ingeneralappearance, like two round wires twisted together.

Instead of making the edges circular in section they may be square, asshown at c c,

" Fig. 3, or elliptical as shown at Figs. 4 and 5;

or the web may join the beaded edges with easy curves as shown at Fig.6, instead of with sharp corners as shown in the other views. These fewmodifications in the shape of the band are given merely to indicate thatany form of section may be adopted in the twisted band, the selectionbeing a matter of taste and somewhat governed by the use to which it isto be applied.

Of the many uses to which this twisted band may be put, I may mentionfor purposes of ornamentation and to make wire fences, for which purposeit is well adapted, being strong, light and easily applied.

The application to a box, g, Fig. 7, for binding the same, will bereadily understood, the nails h It, being driven directly through theweb I) without previously puncturing the same, and by reason of the bandbeing one piece of metal, that is, the beaded edges and central webintegral, the nails may be driven through the band close to its ends andhave a firm hold therein, as well as protecting the extreme ends byforcing them into the wood.

It will be understood that bands, made as hereinbefore described, have auniform appearance throughout and on both sides, because the beads orthickened edges extend equally beyond both faces of the central web. Itis evident that if the beads, made either solid or hollow, project onlyon one side of the strip leaving the other side flat and plain, that thestrip, when twisted, will, for many purposes, be as useful as if it hadthe beads on both sides.

Having now described my invention, what I claim, and desire to secure byLetters Patent, is

1. A twisted solid metal band consisting of an unbroken central web andbeaded edges.

2. A twisted metal band having beaded 'or In testimony that I claim theforegoing as V thickened edges projecting on both sides of my inventionI have signed my name, in pres- IO a thin central unbroken web andintegral ence of two witnesses, this 23d day of April,
